Change of brainstem auditory-evoked potential in vertebrobasilar transient ischemic attack patients

Mohan Rajendran, Subashini Selvakili, K Ganesh Chandra Kaladharan.


Abstract
Background: Transient ischemic attack describes the symptoms of the nervous system which occurs due to insufficient circulation that lasts for <24 h. Its clinical manifestations tend to disappear quickly and it is also considered as an indicator of stroke. Brainstem auditory-evoked potentials are responses of the brainstem by auditory stimulation. Vertebrobasilar (VB) transient ischemia can cause brainstem ischemia which can induce BAEP changes. Hence, it becomes necessary to evaluate the electrophysiological changes in VB transient ischemic attack (VBTIA) patients for early detection of neuronal changes and prevention of full-blown stroke.

Aims and Objectives: The aim of this study was to compare the changes in brainstem auditory-evoked potential in VB TIA patients with normal subject.

Materials and Methods: Auditory-evoked potential was recorded in 40 patients with VBTIA and 40 normal control groups. This study was conducted at the Research Laboratory, Department of Physiology, Thanjavur Medical College, Thanjavur.

Results: The absolute latency of wave V was prolonged and a reduction in amplitude of wave V was observed in patients with VBTIA and it was found to be statistically significant.

Conclusion: This study is very much useful to identify the early detection of the progression of stroke in VB TIA patients. Further studies are required to evaluate the correlation between the electrophysiological parameters and progression into stroke so that preventive measures can be used to prevent early involvement of Stroke.

Key words: Brainstem Auditory-Evoked Potential; Vertebrobasilar Transient Ischemic Attack; Absolute Latency
